1 Claim. 1

This invention relates to improvements in air pressure chip collector units.

An object of the invention is to provide an improved air pressure chip collector unit for removing metal chips from drilling, reaming or tapping holes.

Another object of the invention is to provide a portable chip collecting unit operatively connected with a source of air under pressure for inserting in a hole which has been drilled, reamed or tapped, and by admitting the air under pressure to the unit, will blow the metal chips from the hole into the collecting unit.

A further object of the invention is to provide an improved air pressure chip collector unit which will be highly efficient in operation and relatively inexpensive to manufacture and produce.

Other objects will appear as the description proceeds.

' In the accompanying drawings which form a part of this application,

Figure 1 is a perspective view of the improved air pressure chip collecting unit;

Figure 2 is a sectional view taken on the line 2-2 of Figure 1;

Figure 3 is a sectional view taken on the line 33 of Figure 2; and

Figure 4 is a sectional view taken on the line 4-4 of Figure 2.

Like characters of reference are used throughout the following specification and the accompanying drawings to designate corresponding parts.

In carrying out the invention, there is provided an improved air pressure chip collecting unit for removing metal chips from drilled, reamed or tapped holes including a cylindrical body I having a rounded bottom 2, and is open at the top 3.

A centrally disposed opening 4 is formed in the bottom 2 of the body I and is threaded to support the threaded lower end 5 of the upwardly extending chip discharge pipe 6 which terminates a short distance below the top of the set depending flange 25 for fitting over the top 3 of the body I. The pin III will lock in the seat 9 when the cover II is placed on the body I and rotated.

A series of air vent ports l2 will be formed through the cover II to permit the escape of the air under pressure when said unit is operated.

An inverted cone-shaped deflector I3 is supported at the inside top of the cover II, and a long small air discharge or inlet tube or pipe I4 will be disposed axially therethrough extending through the top of the cover II and axially through the chip discharge pipe or tube 6.

The upper end of the air inlet pipe I4 is headed as at I5 and is supported in the threaded bushing I6 extending through the top or cover I I, and is secured by the threaded nut I'I disposed on its lower end, and by the internally threaded collar l8 disposed on its upper end.

A supply pipe [9 for the air under pressure is connected to the upper end of the air inlet pipe I4 by means of the externally threaded packing nut 20 which is disposed about the pipe I9 and screwed into the threaded collar I8.

In operation, after a hole 2| in the metal work 22 has been drilled, reamed or tapped, the unit is placed to cover the top of the hole and air under pressure is admitted through the pipes I9 and I4 to blow the metal chips which have accumulated in the lower portion 23 of said hole upwardly through the chip discharge pipe or tube 6 to hit against the cone-shaped baflle or deflector I3 to drop down into the bottom of the body I. When the body is nearly filled with chips, it will be emptied by removing the cover I I.

From the foregoing description, it will be apparent that there has been devised and provided a highly efficient form of air pressure chip collecting unit. I I

While the preferred embodiment of the instant invention has been illustrated and described, it will be understood that it is not intended to limit the scope of the invention thereto, as many minor changes in'detail of construction may be resorted to without departure from the spirit of the invention.

Having described. the invention, claimed as new is:

An air pressure chip collector unit comprising a cylindrical body having a rounded bottom, a dome-shaped cover removably secured thereto by means of a bayonet slot on said body and cooperating pin on said dome-shaped cover, a chip discharge tube mounted vertically and axially through said body and attached at its lower what is end to the rounded bottom portion of said cylindrical body and terminating short of said cover, anair tube supported by said cover disposed axially and centrally within said chip discharge 'tube, said air tube being attached at its upper end to said cover and arranged to de- 7 pend'downwardly and centrally through said chip discharge tube, means for supplying air under pressure to said air tube, an inverted cone-shaped deflector supported on the underside of said cover, and said cover being provided with air vents positioned adjacent the base of said conee shaped deflector and out of the path of dis charge of said chip dischargegtube;
